Application filed December 8, 1911. Serial No..66e,549.

To all whomc t may concern:

' Be it known that I, ALBERT J. M'oCaULnY, a citizen of the United States, residing at St. Louis, lvlissouri, have invented a certain new and useful Improvement in Car-Trucks, of which the following is-a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, in which Figure 1 is a side elevation, partly in section, of a portion of a car truck embodying .the' features of this invention; Fig. 2 is a pla n view, partly in section, of the parts shown in Fig. ,1; F1g. 3 IS a section taken 0f the side frame being broken away; Fig. l

with a spring seat is aperspective view of a bolster hanger; Fig. 5 1s a perspective view of a rockable member adapted to be fitted to the bolster hanger; and F ig. (l is a perspective view illustrating a modification.

This invention relates to improvements in car trucks of the lateral motion type, 'one of the objects being'to produce an eilicient lateral motion device which will allow the bolster to move laterally Withrespect to the truck frame and cause the bolster to return to normal position after such movement.

.Another objectis to provide a car truck having a bolster of thestandard type and a truck frame ofthe standard type combined.

with a lateral motion device which allows -the bolster to be very easily fitted to or removed from'the truck frame.

In the accompanying drawings -A., designates a portion of a well known type of truck frame which is shown merely to illustrate thefunction of the lateral -motion devices, it being understood that this invention is not in any way limited to a truck frame constructed as herein shown. here I refer to a truck frame In the claims, I

mean to include a pair of side frames connected together, or any other suitable or desirable truck frame structure. However, as this invention may; be used in connection with many well known truck frame structures, Ido not deem it necessary to show or describe .a complete truck frame.

The truck frame herein shown is provided ing opening 2.

3 designates springs mounted. the, srr e'ss atl anrlsaaaqsated y erratical y 1 and a bolster re'ceiv-' movable spring plate 4, said plate havinglugs a which are slidably fitted'to the side walls 6 of the opening 2. Curved seats 7 are preferably formed on the top face of the spring plate 4. to receive rockable members 8.

H designates bolster hangers resting on the rockers 8 and fitted toa bolster B. Each hanger H constitutes-a bolster support and is preferably provided with a flange 9 upon which the bolster is seated. the usual lugs or column guides 10 on its side faces and the hangers H are preferably The holster hasfitted to the sides of the bolster between these lugs (sceFig. 2). The bolster hangers H and the rockable members 8 constitute a bolster carriage which allowsthe bolster to move laterally with respect to the truck frame and the hangers H beingcarried by the bolster during such lateral movement have 'abutments 11 adapted to engage the truck frame to limit; the movement of the bolster.

The rockers 8 are compression members and preferably substantially heart-shaped as seen in Fig. 5, each of said rockers having three or more curved faces located in different vertical planes and adapted to engage curved seats on the spring plate 4 and hangers H. The hangers H move with the bolster during the lateral movements pre-' viously referred to, while the rockers 8 to the peculiar shape of the rockers 8 they are normally held in the position shown in' Fig. 3 by the weight of the bolster andpar body but when the bolster moves f laterally one 1f the extensions 8 on each rocker .1110 is away from its curved seat on the hafger H, and when the force causing such lat ral movement has ceased the rockersand the bolster automatically return to the position seen in Fig; 3.

The bolster carriage shown in Fig. 6 :is mounted on a vertically movable spring plate 4. having lugs 5 fitted to the truck frame members ,6. erably provided with curved seats 7 for the reception of circular rockers 8 upon which the bolster hanger H is mounted. This bolster hanger comprises-ahorizontal bolsterseat 12 and vertical side .portionsarice The spring plate 4 is pref ranged between the bolster and the truck frame members .6. The bolster (shown in dotted lineslhas. lugs 10 whichinterlock .lliltlllltal ae i E1... an athe hanger: s we vided with abutment's 11 adapted to engage the truck frame members 6 to limit the movement of-the bolster. r

Having thus described the invention, what is'claimed'as new and desired to be secured by. Letters Patent is v 1. A lateral motion car truck comprising a frame, a bolster movable laterally with respect to said frame, and a lateral motion device supporting said bolster, said lateral motion device including bolster supports at the sides of the bolster, and rockable compression members upon which said bolster supports are mounted.

2. A lateral motion car truck comprising a frame, a bolster movable laterally with respect to said frame, and a lateral motion device supporting said bolster, said lateral. motion device including bolster supports in the form of hangers and rockable members upon whichsaid hangers are mounted.

3. A lateral motion car truck comprising a frame, a bolster movable laterally with respect to said frame, and a lateral motion device supporting said bolster, said lateral motion device including bolster supports in the form of hangers fitted to the bolster, and

rockable compression members upon which said hangers are mounted.

4. A lateral motion car truck comprising a'frame, a bolster movable laterally with respect to said frame, said bolster having lugs on its side faces, bolster supports carried by the bolster and fitted between said lugs, and roc'kable members upon which said bolster supports are mounted.

5. A lateral motion car truck comprising aframe, a bolster movable laterally with respect to said frame, springs supported by said frame, and a lateral motion device supported by said springs, said lateral motion device including bolster supports provided with abutments adapted to engage said frame, and rockable members upon which said bolster supports are mounted.

6. A lateral motion car truck comprising a frame, a bolster movable laterally with respect to said frame, springs supported by said frame, a vertically movable spring plate resting on said springs, and a lateral mo-- tion device supported by said vertically movable spring plate, said lateral motion '(lOVlCG ncluding rockers on said spring plate, and bolster supports in theform of nmgers resting onsa'id rockers.

7. A lateral motion car truck comprising a frame, a bolster movable laterally with respect to said frame, springs supported by said frame, a vertically movable spring plate resting on said springs, and a laterahmomovable spring plate, said lateral motion device including rockers fitted to said sprin plate, and bolster supports in the form 0 hangers fitted to the side faces of the bolster and resting on said rockers,

8. A lateral motion car truck comprising 10. A lateral motion car truck comprisinga frame, movable bolster supports in the form of hangers provided with abutments .60 tion device supported by said vertically adapted to engage said frame, movable members upon which said hangers are mounted, and a bolster carried by said hangers.

11. '-A lateral mot-ion car truck comprising a frame, springs supported by said frame, a vertically movable plate supported by said springs, roekable members resting on said plate,bolster supports resting on said roclzable members, and a holster carried by said bolster supports, said bolster supports being fitted, to the side faces of the bolster, and provided with abutments adapted to engage said frame.

12. A lateral motion car truck comprising a frame, springs supported by said frame, a

vertically movable plate supported by said i springs, rockable members resting on said plate, bolster supports resting on said rocln able members, and'a bolster carried by said bolster supports, said bolster supports being fitted to the side faces of the bolster.

In testimony whereof I hereunto alfix .my signature in the presence of two witnesses, this 6th day of December, 1911.
